1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ زُرَارَةَ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ (عَلَيْهِ الْسَّلام) يَقُولُ قَالَ رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه)
إِذَا شَكَّ أَحَدُكُمْ فِي صَلاَتِهِ فَلَمْ يَدْرِ زَادَ أَمْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ وَسَمَّاهُمَا رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه) الْمُرْغِمَتَيْنِ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ibn ’Udhaynah from Zurarah who has said the following: “I once heard abu Ja‘far 
, say,
‘The Messenger of Allah has said, “If one of you doubts in his Salah (prayer) and does not know if he has increased or decreased, he performs two Sajdah (prostration) while sitting.” The Messenger of Allah has called it humiliating (Satan).’”
